Hi Xianrong and Gildas,

this method works, but is a little bit outdated. Please use the setup_r_environment like used here:

https://github.com/galaxyproject/tools-iuc/blob/master/packages/package_dese...

You can use this script with small modifications to create you such a file from scratch:

https://github.com/bioarchive/aRchive_source_code/blob/master/get_galaxy_too...

At least to get started.

An other possibility is to use conda dependencies. So if you R package is already in conda/bioconda you don't need a tool_depenencies.xml file at all. Just specify the requirement tag in your tool with the conda package name and version and activate conda in Galaxy. This will do the trick. -> Only available in 16.01.

Ciao, Bjoern

Hi,

For me, three solutions :

• You can find existing packages which will install your library

(https://testtoolshed.g2.bx.psu.edu/view/jeltje/package_dnacopy_1_40_0/118417...). So you will just need to link a requirement (https://wiki.galaxyproject.org/Admin/Tools/ToolConfigSyntax#A.3Crequirements...) and a tool_dependencies.xml file

• If not, you can write your own package. But thanks to Ross Lazarus,

to deal with dependencies of dependencies of dependencies, there is a tool for that https://testtoolshed.g2.bx.psu.edu/view/fubar/biocdepgen_r_3_1_2/faafc60f3d6...

• If you lack of time, you install R and needed libraries on your serveur.

Unfortunately, I can’t explain you why you couldn’t install your library through your script because R use to allow installing in the user home.

Hi, I am trying to package an R script (that requires certain R packages) into a galaxy tool. Any advice would be deeply appreciated!

I have tested it on planemo and it works. When I tried the version I uploaded onto the toolshed, I got an error saying that the R packages do not exist. I next added the following lines to the R script:

source("https://bioconductor.org/biocLite.R")

biocLite()

biocLite(c("DNAcopy","preprocessCore"))

and I got the following error when running the installed tool on galaxy:

Installing package(s) ‘DNAcopy’, ‘preprocessCore’ Warning in install.packages(pkgs = doing, lib = lib, ...) : 'lib = "/usr/local/lib/R/site-library"' is not writable Error in install.packages(pkgs = doing, lib = lib, ...) : unable to install packages Calls: biocLite ... .biocLiteInstall -> .reposInstall -> install.packages Execution halted ___________________________________________________________ Please keep all replies on the list by using "reply all" in your mail client.
